The big sea's littlest mischief-maker, Oona, is back in another delightful tale from New York Times bestselling author Kelly DiPucchio and Coretta Scott King Illustrator Award winner Raissa Figueroa.

Oona loves to share her inventions with her friends. They're big and bold and LOUD--just like her! But there's one underwater creature who doesn't seem to enjoy Oona's company, or her creations.

Stanley the shark! He doesn't care for her squeaky unicorn. And he's far too busy for the Sea Horse Carousel. And oh GOODNESS! Oona's latest hopping, chopping, and popping inventions just make him angry.

Oona may not know what Stanley likes, but she does know what he doesn't. And maybe that's a good place to start. Because mermaids never stop trying...not when there's a friend out there to make.
